Abstract

The utility model relates to an external fixing frame for limb fracture, which comprises a supporting rod with screw threads, an upper mounting ring and a lower mounting ring which are fixed with the supporting rod and fixing needles on the mounting rings. When the utility model is used, the fixing needles are directly screwed into the bone cortex by a handle without a bone drill, providing convenience for operation; meanwhile, the fixing needles do not penetrate the medulla cavity and the cortical bone at the opposite side so as to have little injury on the bone, which is favorable for the restoration of patients. The fixing needles of the fixing frame for limb fracture can be inserted from different directions as required, therefore the utility model has good fixity, stability and difficult slipping.

Description

External fixing frame for fracture of four limbs

This utility model relates to a kind of medical apparatus and instruments, is specially a kind of four fracture external fixers.

Existing external fixation of fracture frame, usually include a fixed mount, on fixed mount, be provided with locking pin, locking pin thrusts in the sclerotin, thereby play fixation to fracture site, but existing its locking pin of external fixation of fracture frame only is that folk prescription is to thrusting, can not play comprehensive fixing to fracture site, the fracture site that connects is easy to generate angulation deformity, and at first to use bone drill that cortical bone and bone cavity are bored thoroughly in use, and then locking pin is inserted, so not only make troubles to operation, and bring misery, patient's recovery after being unfavorable for simultaneously to the patient.

The purpose of this utility model is for providing a kind of external fixation of fracture frame easy and simple to handle, fixedly good reliability.

This utility model is to adopt following measure to realize: these four fracture external fixers, comprise screwed support bar, with support bar fixed on, the undercarriage ring, wherein the frame ring is for having the annulus of a plurality of screws on it, cooperate with open hole on the frame ring and to be provided with screwed locking pin, fixing between frame ring and the support bar by square head screw and last, following setscrew nut is finished, square head screw cooperates with screw on the frame ring, on the square toes of square head screw, have the circular hole that cooperates with support bar, square head screw on the support bar by on, following setscrew nut location, relative position between support bar and the frame ring can be adjusted according to different fracture sites.

This utility model directly is screwed into cortical bone with locking pin in use without bone drill with handle, and this brings convenience to operation, and locking pin does not penetrate medullary cavity and offside cortical bone simultaneously, and is light to the damage of bone, is easy to patient's recovery.The locking pin of this fracture fixator can thrust from different directions, so its stationarity, good stability, is difficult for slippage.

Accompanying drawing 1 is this utility model structural representation;

Accompanying drawing 2 is the partial structurtes signal;

Accompanying drawing 3 is this utility model user mode figure.

In conjunction with the accompanying drawings this utility model is further described as follows: four fracture external fixers described in the utility model, include three screwed support bars 1,2,3 and with each support bar fixed on, undercarriage ring 4,5, for alleviating the weight of fixed mount, support bar is a hollow pipe, the frame ring is for having the annulus of screw 6 on it, frame ring 4,5 diameter can be according to upper limb, lower limb and four s' thickness is selected different sizes for use, cooperate with open hole on the frame ring and to be provided with a plurality of screwed locking pins 7, fixing between frame ring and each support bar by square head screw 8 and last, following setscrew nut 9,10 finish, have the circular hole that cooperates with support bar on the square toes of square head screw 8, square head screw is screwed into screw on the frame ring, each support bar penetrates the circular hole on the square head screw square toes, be screwed into, following setscrew nut, on adjusting, on following setscrew nut can change, distance between the undercarriage ring, on, locking pin on the undercarriage ring directly is screwed on the fracture site from different directions, under cortical bone, thereby reach fixed purpose, this utility model is because support bar is angular distribution, therefore, can prevent the fracture site angulation deformity, also can adjust post position at any time and correct angulation deformity.

Claims

1, a kind of four fracture external fixers, comprise screwed support bar, with fixed upper and lower the ring of support bar, it is characterized by: the frame ring cooperates with open hole on the frame ring to be provided with screwed locking pin for having the annulus of a plurality of screws on it.

2, four fracture external fixers as claimed in claim 1, it is characterized by: fixing between frame ring and the support bar finished by square head screw and upper and lower setscrew nut, square head screw cooperates with screw on the frame ring, have the circular hole that cooperates with support bar on the square toes of square head screw, square head screw is located by upper and lower setscrew nut on support bar.

3, fixed mount as claimed in claim 1 or 2 is characterized by: screwed support bar is a hollow pipe.
